How to shoot the snow scene? [Reprinted]

When the whole earth is covered with snow, please pick up your camera and turn this rare scenery into eternity. However, in such a shooting environment, photographers have to undergo more tests, they need to keep their fingers flexible at all times, and the cold climate may also affect the camera itself. If the temperature is too low, the battery used by the camera may be greatly affected, and it is very difficult to find the subject as far as possible to protect the camera lens from the "bath" of snowflakes and ice particles, because the heavy snow will hide everything deeply and it is difficult to highlight the beauty of the scene details. It is difficult to control the exposure of the camera in a snowy environment. Shiny background colors usually lead to underexposure of images. To deal with these problems, photographers must be proficient in using cameras, and have enough patience and meticulous professionalism. Like the traditional 35mm camera or media camera, the exposure control of the camera is always based on the light reflected from the scene. However, shooting snow scenes is incompetent. The photographed snow scene is no longer the white that everyone admires, but presents a grayish white, which greatly affects the image effect. At this time, you should adjust it slowly, such as opening the lens aperture (or adjusting the shutter speed) and carefully adjusting the settings. With the continuous improvement of the settings, you will find that the photographed snow scene will gradually return to its original color. But these operations are easier said than done, because it is difficult for photographers to accurately grasp the intensity of light, and the reflective intensity of the same snow scene, cloudy day and sunny day is also very different. When shooting a snow scene, there is no general exposure rule, so we can't look at it with a fixed eye. How can I master the best exposure control when shooting snow scenes? Generally speaking, there are two ways to ensure that we can achieve the best exposure when shooting. One is to use some objects as reference objects, such as gray camera bags, jeans, tree trunks or stones not covered by heavy snow, because they can receive the same intensity of light as the scene. After selecting the reference object, you can manually set the lens aperture and shutter speed to achieve the best shooting effect. Remember not to use automatic exposure mode. If there is no dark reference nearby, I suggest you consider this scheme: first buy a piece of cloth the same size as Kodak gray card and sew it on the camera bag, so that it can be used as a reference everywhere, which is economical and convenient. The second method is to use the attached photometer to test the light intensity, because this photometer can determine the light intensity according to the light in the sky, without considering the reflectivity of the scene to the light, so the snow scene will not affect it. The method is simple. Just aim the hemispherical part of the photometer at the camera lens and press the button, and the correct light intensity will be displayed on the display screen. But pay attention to ensure that the light falling on the photometer must be the same as the light falling on the scenery, so make sure not to stand in the shadow when testing. Electronic optical equipment for camera protection At present, many cameras are equipped with electronic optical equipment. Although the function of the camera has been greatly improved, the battery of the camera may be "turned off" at any time at low temperature, which will affect the operation. When not taking pictures, it is best to cover the camera under the coat, so that the temperature of the fuselage will not be too low. We have to do this to ensure the normal temperature of the battery. When a tripod is needed, it is difficult to disassemble, so some chemical heating equipment is usually placed at the bottom of the camera. In order to protect the camera lens from being damaged by ice and snow particles, it is recommended that you use the lens curtain, and the camera filter can also be well protected. (2) The area of snow determines the exposure: The exposure of snow photography mainly depends on the proportion of snow in the picture. This painting is full of snow. If the central focus is used for average metering, the exposure compensation will increase, otherwise it will decrease. The built-in exposure meter uses 18% standard gray scale to determine the exposure. If the picture is full of bright snow, you must add 2EV exposure, otherwise you can't reproduce the effect seen by the naked eye. If you add 2EV exposure when the picture has blue sky, it will be overexposed. At this time, you should add lEV exposure. If the sky is blue, there is no need for exposure compensation. When the blue sky and white snow account for half of the picture, you can add 1.5EV for exposure. The snow surface reflects the color of the sky, and the exposure compensation adjusts the color: although the snow is white, under different time, weather and lighting conditions, the snow surface will show different colors because of the change of light. The light is warm in the morning and evening, and the snow will be orange-red; On sunny and cloudy days, the light is cool and the snow surface is blue. After sunrise, sometimes the snow will be lavender. In order to show the color of snow, it is necessary to compensate the exposure properly. In order to show the same snow color as the naked eye, the exposure compensation amount is 1EV in the morning and evening under warm light conditions, generally 0.5EV, and lEV under sunny or cloudy light conditions, mainly cyan tone. Reflect the snow scene in a large area: the "expression" of the snow scene is ever-changing, so all surrounding factors need to be considered when deciding the exposure. In the case of backlight, there will be a large area of silver light on the snow surface in addition to the strip-shaped strong reflection light mentioned above. If the camera measures light in this area, the snow surface will be photographed in gray, which requires more exposure. When the picture is full of white snow and the silver light area is large, 2EV exposure should be added. If there is ice in the picture, because the ice is brighter than snow, the camera will measure the light according to the brightness of the ice, so to increase the compensation amount, it is best to take care of the texture of ice and snow and balance the two aspects. In the morning and evening, the snow surface irradiated by warm light will shine with golden light, especially when the snow surface is irradiated by strong sunlight, the contrast is large, the snow surface appears hard and bright, and the dark part is slightly dark. In order to make the snow softer and the dark part richer, the compensation amount can be controlled between 1.5-2EV. Reference exposure compensation metering+experience = appropriate exposure: when shooting snow scenes, you can refer to the above reference exposure compensation, and generally you can get appropriate exposure. However, the conditions such as the amount of snow and light vary from place to place, and the specific occasions and surrounding environmental conditions vary widely, which may increase or decrease in actual shooting. Photographers should be good at accumulating data and experience in this field in order to shoot snow scenes with ease. Central focus average metering: snow photography is the best: in multi-frame metering mode, the camera calculates the exposure after metering all areas of the screen, although there are some errors, it is relatively accurate. In other words, when using multi-frame photometry, the exposure compensation range is very small, which is not easy to master, while the center-focused average photometry is a weighted photometry with the center of the picture as the key area, and the exposure compensation range is relatively large, which is easy to master and obviously more practical.
